rlhis invention relates'to certain new and useful improvements in cultiv-ators, and it has for its objects,'amo1ig` others, primarily to provide simple and efficient durable means whereby the driver may readily shift the traction wheels and the cultivator beams laterally .as'may be desired- This-movement is lsimultaneous, the movable beams being lmovable relative to thejintermediate and outer `fixed beams,and the wheels move 1in unisonA therewith by connections Vwhich insure proper relation between the parts.

-VIt has fora furtherl object to providean improved device of this genera-l character whereby better results are more readily kvobtained, the construction and arrangement be- -V f A'lhe-invei'ition hasfor a further object vto wheels. n y

Other objects and advantages of the invenprovide simple yet eflicient mountings'-and connections for the movable'beams and the operating ymechanism so as -vto, lessen the exertion necessary to readily throw theparts Vinto desired position and,'at the same time materiallylessen the weightof ythe cultivator,

or its movable parts, the movable 'beams moving relative to the outer and Vinte1 1nediate beams, thus requiring less power to operate the same. As the movable beams are shifted and the wheels shifted simultaneously therewith, the relatively lixedbeams fellowithej angleorinclination assumed by the` wheels,

and thus the outer beams automaticallyfol low the inclination tion will hereinafter-appear and the novel features thereof will be particularly pointed out in the appended claims.- Y' l The finventio'n, in its preferred form, `is clearly illustrated inthe accompanying drawings, which, with the numerals of reference member 'of the movable beams.

th'ebeamsS, and thelwheelsfto move 'in'unij gives angular movement to the wheels and i to the movable beams 8.

- Each beam 7 is provided with the lateral member 16 (see Fig. 3)'through which is `mounted, for vertical movement, a member '17 secured at its upper end in any suitable manner, to the transverse vmembers 9. The

upper ends of the members 17 are pivotally mounted as at 18, see Fig. 2, and are provided with projections or the like 20 which are engaged in slots 19 in the members v20au of.

such a nature as to permit of adjustment of the members 17 to adjust the rear end of thev beams farther apart or closer together as occasion may require.

The forward ends of the beams 8 arepivotally mounted on lateral projections from the axes of the beams 7 so as to move vertically in unison therewith but such forward ends are carried by a knuckle-jointed member 21 (see Fig. ,sothat while the beams 7 and 8 may be moved vertically, simultaneously, the beams 8 are free to have lateral movement on theirpivot independently of the adjacent beams. The knuckle joints f as well Yas the members by which they are carried frame and mounted in said bracket is a shaft 24'carrying thereon a sprocketv wheel 25 over which passes a sprocket chain 26 .or other Y 'suitable ligament, the ends of which are connected as at 27 to the bars 28 and 29, from `which depend the pedals 30 and 31. These members 28 and 29 are pivotally mounted at theirforward ends so yas to lbe actuated vertically in one direction or the othery by pres sure ofthe footfupon the pedal.

`The forward end of the shaft 24 is suitably mounted for revolution in a bearing 32 (see Fig. 1) and upon'this end of the lshaft is a circular member, around which passes a chain or other ligament 34, the Yends of which are vcrossed as seen in Fig. 8, and .the ends of said member 34 are attached'as atV 35and 86 to suitable means on vthe member 9 as shown clearly in Fig. 3, so that when pressure is applied to one' or the other of theY pedals 8O or 31, the member 9V` will be moved to the right or left, and'simultaneously with this movement Vof' the member9, the wheels and 'the' beams 8'give corresponding movement-,while the beams 7 ,remainstationary.V As the front ofthe wheels are moved out.- wardlyat 'anangle, sayto the right, compared with the frame, the adjacent beams "areY movedinthe same direction, and aspressure isapplied upon the Vother pedalfthe wheels are given simultaneous movement'ati,841,2oe

the opposite angle, and the movable beams 8 follow such angularity.`

When desired, all of the beams can be raised byl manipulation of thelever 6.

In order to provide for taking up slack or regulating the tension of the ligament 34, the members 35, 36 to which the yends thereof are attached after passing. aroundthe member 3 3, the said members are movable in slots 14. Their shanks 37 are screw-threaded as at 38`with their ends passed through the mem* bers 89 depending from the member 9 and carry upon their ends nuts 40, as seen in Figs. 2 and 43, sothat adjustment of these nuts on the ybolts readily take care of any slack in the member 34, and thus proper tension is placed upon theligamentor chain 34 to insure proper location of the shaft24r,

` It is toy be'noted that by manipulation of `the shaft'24c by the feet of the operator through the connections above described and shown, thepivotally mounted `beams are moved llaterally and `at the same time the wheels are caused to move therewith, butthe relatively xedlbeams 5 and 7 do not move, and V`their original krelative, positions are not changed, for whileveach set of beams upon `each side of the fcultivator may be raised or lowered together with the beams 8, the latter are moved laterally withoutlateralmove- Yment ofthe beams and 7.

Theoperation and relative movements lof the parts, having beenV liereinbefore clearly stated, a further description thereof does not seem necessary. v
